• Protocol: The value compared in the IPv4 header Protocol field or IPv6 header Next Header field.
Possible values are 0x6 (TCP) and 0x11 (UDP). This field is relevant only if the Ignore Protocol flag
is cleared.
• Port: The value compared in the Destination Port or Source Port field of the TCP or UDP header.
• Port Index: Indicates which port filter is reported by the response. Should match the Port Index in
the command.
Table 10-55 describes the fields in the Get Port Flags field.
10.6.3.14.5 Enable Unicast Infrastructure Filter Command (Intel Command 0x25, Index =
0x4)
A Management Controller uses the Enable Unicast Infrastructure Filter command to configure a
Network Controller to forward copies of network infrastructure packets to it. Network infrastructure
packets contain messages that are necessary for operation of the network infrastructure layers (e.g.,
DHCP, ARP, and DNS messages). This is required when the Management Controller shares an IP
address with the Host. In this case, both the Host and the Management Controller need to process the
messages, so the Network Controller must forward the packets to both the Management Controller and
the Host.
This command should be applied only after a MAC address is added using the Set MAC Address NC-SI
command.
All the IP addresses added through the Set IP command before this command is given are considered
as IP addresses of the management controller for the purpose of this command.
If a Set IP command is received after this command was received, the list of IP address is not updated
and this command should be given again.
